An arsenal of weapons including at least six bombs, handguns, and a rifle were found at the scene of the Watertown shootout between police and the two Boston bombing suspects Friday. A lone police officer first came in contact with Tamerlan and Dzhokhar Tsarnaev around one in the morning, Friday, and before he could call for backup, the brothers jumped out of their car and began shooting. Five other officers then arrived to what Police Chief Edward Deveau described as "a very tight area" to help in the shootout, during which an estimated 200 shots were fired in a 5-to-10-minute period and one of the brothers threw a pressure cooker bomb at the officers.
